WINDOW-SASH FOR STREET-CARS.

SPECIFICATION forming part of Letters Patent No. 784,706, dated March 14, 1905.

Application filed January 13, 1903. Renewed November 9, 1904. Serial No. 231,985.

To all whom it may con/cern:

Be it known that I, EDWARD T. ROBIN- soN, a citizen of theUnited States, and a resident of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in INindow-Sashes for Street- Cars, of which the following is a specification.

My invention relates to window-sashes for street-cars, and has for its principal objects to provide for the raising and lowering of the upper sash independently of the lower sash, also to provide for the convenient removal of the upper sash, and also to attain certain4 advantages hereinafter disclosed.

My invention consists in the construction and arran ements of parts hereinafter described an claimed.

In the accompanying drawings, which form part of this specification, and wherein like symbols refer to like parts wherever they occur, Figure l is a front view of a car-window equipped with my invention. Fig. 2 is a cross-section thereof on the line 2 2 of Fig. 1. Figs. 3 and 4 are side and horizontal sectional views of the mounting-bolt. Fig. 5 is a detail showing the overlapping portion of the sashes. Fig. 6 is a view of the top stop for the lower sash. Figs. 7 and S are hori- Zontal sections of the window-post on the lines 7 7 and S S of Fig. 2, respectively. Fig. 9 is a detail view of the spring-bolt. Fig. 10 is a detail view of top of upper-sash groove.

In the present construction the car-window has an upper sash I and a lower sash 2. Below the windoweopening the car is provided with an inside lining 3, arranged to form a pocket for the sashes to be llowered into'. The sides of the lower sash fit in grooves 4, formed therefor in the windowposts 5, each of said grooves being formed by a shoulder and a parting-strip 6, provided therefor on the post, as usual. The top sash has bolts or pintles 7, projecting laterally therefrom near its upper edge. These pivotbolts rest in a groove 8, provided therefor in the window-posts. In order to bring thetop sash in proper relation to the lower sash, the upper sash-grooves terminate in downturned portions or sockets 9 in such position that when the pivot-bolts rest therein the top sash will hang substantially vertically, with its lower edge just outside of the top of the lower sash. Each of the grooves for the pivot-bolts extends upwardly-a short distance from the socket 9thus located a suflicient distance to allow the top sash to be raised to clear the lower sash. The pivotbolt groove then extends downwardly at a slight inclination, so as to clear the partingstrip, and then extends parallel with the parting-strip into the sash-pocket. The partingstrip may constitute one wall of said groove. In order to facilitate the removal of the upper sash, it is preferable to mount the pivotbolt in a socket or housing '10, provided therefor on said upper sash, and to equip said socket with a spring 11, adapted to normally press said bolt outwardly into its groove. A lug or finger-piece 12 on said bolt extends outwardly through an elongated slot provided therefor, and this furnishes a convenient means for retracting said bolt7 so as to clear its groove, whereupon the upper sash may be swung clear of the window-post, and thus removed. The lower sash may be removed without interfering with the upper sash simply by removing the parting-strip. For this purpose the inner portion of the window-post is made narrower than the outer portion, so that the sides of the pivot-bolt groove and of the curtain-groove 123 will not interfere with the removal of the lower sash.

As the top sash is merely pivoted, its lower end is liable to be pulled inwardly farther than is desirable. In order to avoid such action, the face-molding 14 of the windowpost may be made of sufficient width to overlap the side edges of the top sash, and thereby constitute a guide therefor.

The upward movement of the lower sash is limited by a metal stop 15, fixed upon the window-post. The side of this metal stop constitutes a lateral stop for the upper sash, which rests on shoulders 16 provided therefor on the posts.

In order to prevent rattling and keep the top sash iirmly seated in its rests, a strong spring 17 is arranged at the top of the window-opening in position to bear against the top of the top sash.

In order to protect the sash-pockets and contents from dirt and extraneous matter, a cover 1S therefor is hinged to the top of the .inside lining and provided With a handpiece for manipulating it.

Obviously the construction hereinbefore described admits of considerable modification without departing from my invention, and I do not wish to be restricted to the specie construction hereinbefore described.

What I claim isl. A car-window comprising posts having stops for upper and lower sashes, the stops for the upper sash being outside of and below the top of the lower sash when in position on its stops, a lower sash and an upper sash, said posts being constructed to permit said upper sash to move upwardly to clear the top of said lower sash when in position on its stops so that said upper and lower sashes are independentlyT movable in all positions oll each sash.

2. A car-window comprising posts provided with a giiide-groove, and having no part inside of said guide-groove projecting laterally beyond the inner wall thereof, and a sash traveling between the posts and provided with retaining-pintles coperating with the said guide-grooves, one of the said pintles being retractable and capable of manipulation when the sash is in its operative position, whereby said sash may be removed without disturbing any part of said posts.

3. A car-window comprising posts each provided with a parting-strip and a guidegroove and having no part inside of said guide-groove projecting laterally beyond the inner wall thereof, a lower sash vertically movable outside of the parting-stri and an upper sash having a IiXed retaining-pintle upon one side and a spring-pressed retractable retaining-pintle upon the other side cooperating with said guide-grooves, said retractable pintle being capable of manipulation when the sash is in its operative position, whereby said sash may be removed. without disturbing any part oll said posts.

4. A car-window comprising posts provided with a giiide-groove extending upwardly, and then outwardly and terminating in a downwardly-extending pocket, and stops for upper and lower sashes, a lower sash, and an upper sash having pintles cooperating with the said guide-grooves, the highest part of the guide-grooves being at least as high above the lower sash when in position on its stop as the pintles are above the bottom of the upper sash, whereby the upper sash is movable independently of the lower sash.

5. A car-window comprising posts provided with a parting-strip terminating in a stop-piece forming a vertical stop for the lower sash and an inner lateral stop for the upper sash, a lower sash vertically movable outside of the parting-strip, an upper sash vertically movable inside of the parting-strip at the lower portion of its travel, and laterally movable' over the parting-strip at the upper portion of its travel.

6. In a street-car, a window comprising movable upper and lower sashes, and a Vfitting on the window-post constituting an inner lateral stop for the upper sash and a vertical stop for the lower sash.

7. In a street-car, a window comprising an upper sash and a lower sash, the window'- posts having grooves located inside of the lower sash, the upper ends of said grooves tending outwardly above the lower sash and terminating in downturned pockets, and pivot-bolts mounted on said upper sash to slide in said grooves, the said posts being con.- structed to permit said upper sash to move upwardly to clear the top o'l` said lower sash so that said upper and lower sashes are independently movable in all positions of each sash.

S. In a street-car, a window comprising an upper sash and a lower sash, the windowposts having grooves located inside of the lower sash, the upper end of said grooves eX- tending outwardly above the lower sash and terminating in downturned pockets, and pivot-bolts mounted on said upper sash to slide in said grooves, and a parting-strip whose upper end is arranged to permit said upper sash to clear it, the said posts being constructed to permit said upper sash to move upwardly to clear the top of said lower sash so that said upper and lower sashes are independently movable in all positions of each sash.

9. A car-window comprising posts having parting-strips stopping short of the top and stops for upper and lower sashes, the stops lor the upper sash being outside ol and below the top of the lower sash when in position on its stops, a lower sash movable vertically outside o'f said parting-strips, an upper sash movable vertically inside of said parting-strips at the lower portion of its travel, said posts being constructed to permit said upper sash to move upwardly to clear the top of said lower sash when in position on its stops so that said upper and lower sashes are independently movable in all positions of each sash.

10. A car-window comprising posts provided with a guide-groove extending upwardly and then outwardly and terminating in a downwardly-extending pocket, and stops IOO the upper sash whereby the upper sash is Inova ble independently of the lower sash.
